Oldest Briton remaining chipper as he marks 112th

His life has spanned parts of three centuries. But extreme age and being confined to a wheelchair didn't prevent Henry Allingham, Britain's oldest living man, from celebrating his 112th birthday in style Friday.

Allingham is also the oldest living Royal Air Force veteran and one of only three British World War I veterans known to be alive.

He was honored with festivities that included a Royal Air Force flyby, a parachute jump, a birthday cake and a visit with local schoolchildren in a gala celebration at Royal Air Force College in Lincholnshire.

"People ask me how I've done it, and I just say that I look forward to another tomorrow," Allingham said.
